Marty, I remember a similar experience while backpacking in the High Peaks Wilderness in 2001. <This was a long time ago and represents how *old* I am :-( >
I believe it was late May/Early June. On day two I was hiking around Elk Lake and I had every conceivable species of flying, biting insect circling me. When I attempted to eat, they were landing on my food. Later that day, I decided to climb Dix to make a high camp, *just to get away from the insects*. I ran across a group of day hikers on my way along the Bouquet River....I literally begged them for bug spray. They gave me a can of Deep Woods Off. It was a giant can, and almost ridiculous in size to be carrying on a backpack, but I was eternally grateful.
The second worst experience was backpacking the Long Path. On a section through Harriman, I must have stuck my hiking pole in a ground nest of yellow jackets, and they swarmed me. It was pretty terrible and frightening, and I suffered alot of stings. It made for a really uncomfortable night. :-(
This summer the bugs are pretty bad. A few weeks ago we were swarmed by black flies on Resolution. Pemi Aussie-Puppy's entire face blew up. Her eyes were almost swollen shut. We had to give her Benedryl to take down the swelling. (BTW, the dose for dogs is 1 benedryl/25 pounds). You know the bugs are bad on your hike when you pray for RAIN to wash them away.
